1. [英语翻译]水方面的 高手来
原文写得很垃圾,真的
楼上的是用GOOGLE翻译的
我给你一篇地道的参考下
Water is the best known and most abundant of all chemical compounds occurring in relatively pure form on the earth’ s surface. Oxygen, the most abundant chemical dement, is present in combination with hydrogen to the extent of 89 percent in water. Water covers about three fourths of the earth’ s surface and permeates cracks of much solid land. The polar regions are overlaid with vast quantities of ice, and the atmosphere of the earth. Carries water vapor in quantities from 0.1 percent to 2 percent by weight. It has been estimated that the amount of water in the atmosphere above a square mile of land on a mild summer day is of the order of 50 000 tons.
All life on earth depends upon water, the principal ingredient of living cells. The use of water by man, plants, and animals is universal. Without it there can be no life. Every living thing requires water. Man can go nearly two months without food, but can live only three or four days without water.
In our homes, whether in the city or in the country,water is essential for cleanliness and health.The average American family uses from 65 000 to 75 000 gallons of water per year for various household purposes.
Water can be considered as the principal raw material and the lowest cost raw material from which most of our farm proce is made. It is essential for the growth of crops and animals and is a very important factor in the proction of milk and eggs. Animals and poultry, if constantly supplied with running water, will proce more meat, more milk, and more eggs per pound of food and per hour of labor. For example, apples are 8796 water. The trees on which they grow must have watered many times the weight of the fruit. Potatoes are 75% water. To grow an acre of potatoes tons of water is required. Fish are 8096 water. They not only consume water but also must have large volumes of water in which to live. Milk is 88% water. To proce one quart of milk a cow requires from 3.5 to 5.5 quarts of water. Beef is 77% water. To proce a pound of beef an animal must drink many times that much water. If there is a shortage of water, there will be a decline in farm proction, just as a shortage of steel will cause a decrease in the proction of automobiles.
2. "专业送水"如何翻译成英文
第5楼胡扯。。。真汗。
作为广告语、标语,不需要用完整句子,主要是简洁明了!
你看看如下标语怎样:
“Drinking water EMS----Clean,Fast,Safe!”
饮用水速递(EMS是特快专递哪国人都知道)----洁净、迅速、安全!

3. 谁有整套纯化水制备系统专业术语英文版的啊
1.蒸馏法,按蒸馏器皿可分为玻璃、石英蒸馏器,金属材质的有铜、不锈钢和白金蒸馏器等。按蒸馏次数可分为一次、二次和多次蒸馏法。此外,为了去掉一些特出的杂质,还需采取一些特殊的措施。例如预先加入一些高锰酸钾可除去易氧化物;加入少许磷酸可除去三价铁;加入少许不挥发酸可制取无氨水等。蒸馏水可以满足普通分析实验室的用水要求。由于很难排除二氧化碳的溶入。所以水的电阻率是很低的,达不到MΩ级。不能满足许多新技术的需要。%D%A %D%A 2.离子交换法,主要有两种制备方式:%Dª. 复床式,即按阳床—阴床—阳床—阴床—混合床的方式连接并生产去离子水;早期多采用这种方式,便于树脂再生。%D«. 混床式(2-5级串联不等),混床去离子的效果好。但再生不方便。%D%A离子交换法可以获得十几MΩ的去离子水。但有机物无法去掉,TOC和COD值往往比原水还高。这是因为树脂不好,或是树脂的预处理不彻底,树脂中所含的低聚物、单体、添加剂等没有除尽,或树脂不稳定,不断地释放出分解产物。这一切都将以TOC或COD指标的形式表现出来。例如,当自来水的COD值为2mg/L时,经过去离子处理得到的去离子水的COD值常在5-10mg/L之间。当然,在使用好树脂时会得到好结果,否则就无法制备超纯水了。 %D%A %D%A 3.电渗析法,产生于1950年[4],由于其能耗低,常作为离子交换法的前处理步骤。它在外加直流电场作用下,利用阴阳离子交换膜分别选择性的允许阴阳离子透过,使一部分离子透过离子交换膜迁移到另一部分水中去,从而使一部分水纯化,另一部分水浓缩。这就是电渗析的原理。电渗析是常用的脱盐技术之一。产出水的纯度能满足一写工业用水的需要。例如,用电阻率为1.6KΩ·cm(25°C)的原水可以获得1.03MΩ·cm(25°C)的产出水。换言之,原水的总硬度为77mg/L时产出水的总硬度则为∽10mg/L.%D%A %D%A 4.反渗透法,目前它是一种应用最广的脱盐技术。反渗透膜虽在1977年 就有了,但其规模化生产和广泛用于脱盐却是近几年的事情。反渗透膜能去除无机盐、有机物(分子量>500)、细菌、热源、病毒、悬浊物(粒径>0.1μm)等。产出水的电阻率能较原水的电阻率升高近10倍。
4. 纯净水和蒸馏水怎样翻译
纯净水就是接近于没有杂质的水,就是几乎纯的H2O。蒸馏水就是通过汽化收集重新得到的水,可能还会有其他的杂质。
有时也互相通用,一个指水的成分,一个着重讲制水的过程。
5. [英语翻译]关于水方面的
The fresh water which can be used only includs these water which flows in the pools ,part of underground water and which is frozen in the iceberg.Though it counts 1.4 billion cubic kilometers ,it is even smaller than one percent of the total water on the earth .
So we should keep it in mind that there are only one percent of the total amount of water can be used by people.So try to image that there are 6 billion people while there are only 1.4 billion cubic kilometers of water,how much water can we own?Due to the significantly growing number of people ,that both people density and the size of cities grow at the same time .Finally we have to face to a big problem ,that is the shortage of water.
Here is the situation of China:
Though China has a pretty abundance source of water,but the situation is stilll not optimistic.The main problems are:
1.water resources uneven distribution
2.water shortage aggravates
3.serious water pollution
When looking at the statistics data of water,we will find that the distribution of water in China has a apparently difference between the north and the south.The place along with and in the south of the changjiang river has 53 percents of the total people,but has 81 percents of the total water.So in the nirth ,there is 47 percents of people but only owns 19 percents of water. Some experts point out that e to the change of nature envrinonment and these human activity ,the source of water in he north will rece while in the south it grows.This trend is really apprent in the last 20 years.This trend is increasing the problem.
Though China owns 2.8 trilllion cubic meters of water,but China also has a big amount of people in the mean time ,so China is also a country which is short of water.For the time being ,the amount of water one person owns on the average is about 2200 cubic meters .This is about one quarter of the average amount of world per capita.What's worse ,the number will drop to 1760 in 2030.
The last aspect is the water pollution .The main reasons of water pollution including the following there aspects:
1.The missing processing of instrial water.
2.The over used of pesticides
3.The pouring living water has not reached the standard.

7. 纯化水制水系统经过石英砂过滤器之后的水口要检验吗
贵公司的纯化水设备工艺感觉后面都是多余的,呵呵。
在软水器和保安过滤器中间设置取水点,其实真没多大意义。
